Find the length of AB

Find The Length Of AB

Answers

Answer 1
x=3
that is the answer
Answer 2

Answer:

AB is 15

Step-by-step explanation:

AB and BC are equal because the line that goes through the triangle is going through at a 90 degree angle, u can see that by the small square, and u know it's in the middle bc of the short lines on AD and DC, the short lines means that they are congruent, so:

5x = 4x + 3

subtract 4x from both sides

x = 3

Now u have x, put it in the equation

5x = 5(3) = 15

DOES ANYONE KNOW HOW TO FIND WHAT SLOPE REPRESENTS??? PLEASE HELP ME

Answers

Answer:

slope intercept form.

Step-by-step explanation:

heres the slope intercept form: y=mx+b.

this equation is what you will use to plot lines on graphs, points etc.

the letter b represents the y-intercept, where the line crosses a number on the y intercept on the graph. for example, an initial payment of 30 dollars.

the mx represents slope, or rate of change. for example, paying 5 dollars an hour.

you wouldn't plug a number to the x, but instead the m, because you'd multiply the m with the x.

Based on your question, I think you are asking what slope is. Slope is the rate of change.

The ratio of Val's savings to Dan is 2:3 at first. After Dan spent P3000.00, Val's saving became 11/3 more of that Dan's remaining savings. What is the total amount of saving the two had at first

Answers

Answer:

P.7500.00

Step-by-step explanation:

We are told that:

The ratio of Val's savings to Dan is 2:3 at first.

Now, Dan spent P3000.00 and Val's saving became 1⅓ more of that Dan's remaining savings.

Let's say the total amount of savings they had at first was x.

Thus;

Val had: 2x/5

Dan had: 3x/5

Now, Dan spent P3000.00.

So amount Dan has left = (3x/5) - 3000

We are told Val's savings is now 1⅓ = 4/3 times that of Dan's remaining savings

Thus; 2x/5 = (4/3)((3x/5) - 3000)

2x/5 = 12x/15 - 4000

Multiply through by 15 to get;

6x = 12x - (3000 × 15)

6x = 12x - 45000

Rearranging, we have;

12x - 6x = 45000

6x = 45000

x = 45000/6

x = P.7500

The distance a spring will stretch varies directly how much weight is attached to the spring if a spring stretches 6 inches with 80 pounds attached how far will it stretch with 55 pounds attached? Round to the nearest 10th of an inch

Answers

Answer:

The spring will stretch 4.1 inches

Step-by-step explanation:

Direct Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality.

Let's call:

y = distance a spring stretches

x = weight attached to the spring

We know when x=80 pounds, y=6 inches, thus:

6 = 80k

Solve for k:

[tex]k=\frac{6}{80}=\frac{3}{40}[/tex]

The equation is now:

[tex]\displaystyle y = \frac{3}{40}x[/tex]

When x=55 pounds are attached:

[tex]\displaystyle y = \frac{3}{40}\cdot 55[/tex]

Calculating:

y = 4.1 inches

The spring will stretch 4.1 inches

Answer:

APtₙ = (n-2)k² + (2n - 3)k + n

Step-by-step explanation:

Given sequence:

-k² - k + 1, k + 2, k² + 3k + 3, 2k² + 5k + 4, ...

We can see apart from the second term all terms are 2nd degree trinomial so it is not a GP.

Let's find the difference: to determine if it is a AP:

k + 2 - (-k² - k + 1) = k + 2 + k² + k -1 = k² + 2k + 1k² + 3k + 3 - (k + 2) =  k² + 3k + 3 - k - 2 = k² + 2k + 12k² + 5k + 4 - (k² + 3k + 3) = 2k² + 5k + 4 - k² - 3k - 3 = k² + 2k + 1

As we see the difference is common and it confirms the sequence is AP.

First term is

a₁= -k² - k + 1

Common difference is

d = k² + 2k + 1

nth term is:

tₙ = a₁ + (n-1)dtₙ = -k² - k + 1 + (n-1)(k² + 2k + 1) =-k² - k + 1 + (n-1)k² + (n-1)*2k + n-1 =(n-2)k² + (2n - 3)k + n

Given a Segment AB find the distance; B = 30 and A = 10

Answers

Answer:

use formula of distance ;

Step-by-step explanation:

d = distance

(x_1, y_1) = coordinates of the first point

(x_2, y_2) = coordinates of the second point

so d is √((x_2-x_1)²+(y_2-y_1)²)

to find the distance between any two points.

taking A as x coordinate and B as y coordinate ie

A= [10,0]; B= [0,30]

[10 is x1 ,0 is y1 ]; [0is x2 and 30 is y2]

putting values in distance formula

√(0-10)²+(30-0)²

= √( -10 )²+(30)²

=[tex]\sqrt[/tex] 100+900

=√1000

= 31.622

the distance between ab is 31.62 or√1000

Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 181.5 square centimeters

Answers

Answer:

The base and height of the solid is 5.5cm

Step-by-step explanation:

Given

[tex]Surface\ Area = 181.5cm^2[/tex]

Required

Determine the dimensions that maximizes the volume

Let the base dimension be x and the height be h

The volume is calculated as:

[tex]Volume =x^2 * h[/tex]

[tex]Volume =x^2h[/tex]

181.5 =x^2h

The surface area (S) is calculated as this:

[tex]S = 2(x^2 + xh + xh)[/tex]

[tex]S = 2(x^2 + 2xh)[/tex]

[tex]S = 2x^2 + 4xh[/tex]

Substitute 181.5 for S

[tex]181.5 = 2x^2 + 4xh[/tex]

Make h the subject:

[tex]4xh = 181.5 - 2x^2[/tex]

[tex]h = \frac{181.5 - 2x^2}{4x}[/tex]

Substitute [tex]h = \frac{181.5 - 2x^2}{4x}[/tex] in [tex]Volume =x^2h[/tex]

[tex]V = x^2(\frac{181.5 - 2x^2}{4x})[/tex]

[tex]V = x(\frac{181.5 - 2x^2}{4})[/tex]

[tex]V = \frac{1}{4}(x)(181.5 - 2x^2)[/tex]

[tex]V = \frac{181.5x}{4} - \frac{2x^3}{4}[/tex]

[tex]V = \frac{181.5x}{4} - \frac{x^3}{2}[/tex]

To get the maximum, we differentiate V with respect to t and set the differentiation to 0

[tex]dV = \frac{181.5}{4} - \frac{3x^2}{2}[/tex]

Set to 0

[tex]0 = \frac{181.5}{4} - \frac{3x^2}{2}[/tex]

[tex]\frac{3x^2}{2} = \frac{181.5}{4}[/tex]

Multiply through by 4

[tex]4 * \frac{3x^2}{2} = \frac{181.5}{4} * 4[/tex]

[tex]2*3x^2 = 181.5[/tex]

[tex]6x^2 = 181.5[/tex]

[tex]x^2 = \frac{181.5}{6}[/tex]

[tex]x^2 = 30.25[/tex]

[tex]x = \sqrt{30.25[/tex]

[tex]x = 5.5[/tex]

Recall that:

[tex]h = \frac{181.5 - 2x^2}{4x}[/tex]

[tex]h = \frac{181.5 - 2 * 5.5^2}{4 * 5.5}[/tex]

[tex]h = \frac{181.5 - 60.5}{22}[/tex]

[tex]h = \frac{121}{22}[/tex]

[tex]h = 5.5[/tex]

So, we have:

[tex]h = 5.5[/tex]

[tex]x = 5.5[/tex]

Hence, the base and height of the solid is 5.5cm

Answers

Answer:

#7.

The domain is {-3,0,4}

the range is {-5,0,1,7}

not a function

#8

D={3,6,12,18}

R={5,7,9,10}

not a function

Step-by-step explanation:

First, 7.

the domain is the all of the x values, in numerical order, listed once, even if it repeats.

D={-3,0,4} (notice how -3 is listed twice; despite that, we only list it once)  

the range is all of the y values, in numerical order, listed once, even if the numbers repeat

R={-5,0,1,7}

A function can have the range (y values) repeat, however, the domain (x values) cannot repeat.

Therefore, this is not a function, since -3 is listed twice.

For 8.

The domain, can be listed as

D={3,6,12,18}

And the range as

R={5,7,9,10}

Notice how it says that if 6 is the input (x), the output (y) can be 5 or 10. Since we said the domain CANNOT repeat, this isn't a function.
